Side-entering type backlight module and display device

An edge-type backlight and module technology, which is applied in the field of edge-type backlight modules and display devices, can solve the disadvantages of thin-shaped design of edge-type backlight modules, large overall thickness of edge-type backlight modules, and reflections. The problem of large thickness of the sheet is to achieve the effect of being conducive to thin design, reducing the overall thickness and ensuring the brightness of the light.

Problems solved by technology

Since the reflective sheet 03 in the prior art is generally made by coating a reflective material on the substrate, and the thickness of the substrate is generally relatively large, the thickness of the reflective sheet is relatively large, which in turn leads to the side-type backlight module. The overall thickness is relatively large, which is not conducive to the thin design of the side-type backlight module

Abstract

The embodiment of the invention provides a side-entering type backlight module and a display device, and relates to the technical field of the display device. The thickness of the side-entering type backlight module is reduced, and the thin design of the side-entering type backlight module is facilitated. The side-entering type backlight module comprises a light guide plate which includes an upper surface for light out, and a lower surface opposite to the upper surface. The lower surface is provided with a refraction coating layer. A refractive index of the refraction coating layer is less than the refractive index of the light guide plate. A reflection coating layer is arranged on a surface of the refraction coating layer far from the light guide plate, and is used for reflecting the light on the reflection coating layer. The side-entering type backlight module is used for the display device.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an edge-type backlight module and a display device. Background technique [0002] With the continuous development of science and technology, people have higher and higher requirements on the thickness of liquid crystal display devices, and the thinning of liquid crystal display devices has become a hot spot pursued by people. A liquid crystal display generally includes a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module is one of the key components of the liquid crystal display device. [0003] Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. figure 1 It is a schematic structural diagram of a side-...
